cluster setup in centos 5.2 using (mpich2)
hello guys, this is 3rd thread related to same issue. but no one replied, now i am tring last chance to someone would help...
Actually i am design parallel computation using beowulf clustering concept, the software i am using 'mpich2'.i have 10 computer, for instance i trying for 2 computer, 1 mater(chipwarequantum) and other 2 node(node1). now i did whatever is available on net i tried those steps but its not working but when i tried this it works [santosh@chipwarequantum]$ mpirun -np 1 a.out Process 0 of 1 on chipwarequantum pi is approximately 3.1415926544231341, Error is 0.0000000008333410 wall clock time = 0.000618 [santosh@chipwarequantum]$ mpirun -np 2 a.out p0_21125: (64.955735) Procgroup: p0_21125: (64.955789) entry 0: chipwarequantum 0 0 /home/santosh/mpich-1.2.7p1/examples/basic/a.out santosh p0_21125: (64.955804) entry 1: localhost.localdomain 1 1 /home/santosh/mpich-1.2.7p1/examples/basic/a.out santosh p0_21125: p4_error: Could not gethostbyname for host chipwarequantum; may be invalid name : 65 setting for this cluster vi mpich-1.2.7p1/util/machines/machines.LINUX # Change this file to contain the machines that you want to use # to run MPI jobs on.
